摘要

To solve the problems of excessive channels as well as separate estimation of the frequency and DOA in array signal processing, a joint estimation method for frequency and DOA of virtual antenna array in space-time domain is proposed. The method only uses a single antenna to collect data in uniform linear motion and form a space-time two-dimensional signal model. Combined with the two-dimensional MUSIC algorithm, the joint estimation of frequency and angle is realized. The effectiveness of the proposed method is verified by theoretical analysis and simulation.
